capable of producing new and valuableiesults.

One object of my invention is a lock in which the revoluble cylinder is made capable of revolution by means of a movement of the pins and drivers in direction parallel to the movement of key insertion.

. Another object of my invention is a lock containing false pins, the movement of which in the direction of key insertion, locks the device.

Another object of my invention is a lock capable of being unlocked by means of a key having bits in angular position with respect to each other.

Another object of my invention is a lock containing a bit chamber in which an inserted key bit is revoluble.

Another object of my invention is a lock in which the key insertion will move a pin rality of pins, unlocking the device, without affecting the position of a plurality of false pins, the movement of which would look the device.

These and other objects of my invention are evident upon a consideration of my drawings and specification.

In a broad way, my invention comprises a casing enclosing a revolubl'e cylinder, within which are a series of pins operative against a series of drivers, the inward movement of the keys moving the pins and drivers in the same direction as the key movement, the movement unlocking the device.

A modified form of the device of my invention contains a single false pin, or a plurality thereof, which is not affected by the unlocking of the device by the movement of the key, but which, if moved inwardly, will lock the device.

The device of my invention also contains a bit chamber in which one ofthe wing bits Specification of Letters Patent. Patented Apr. i1,v 1922.

of a key may be revolved before insertion within the pin chambers.

The device of my invention is operative by means of a keycontainiiig a series of bits and pin-engaging members in angular position with respect to each other. a

In the accompanying drawings a particularfo'rm of the device of my invention is shown as applied to a paddock, but it is evident that the mechanism of my invention can be readily applied to other form of locks, as door-locks, snap-locks, &c.

In the accompanying drawings, illustrating modifications of the device of my invention, similar parts are designated by similar numerals Figure 1 is a rear end View of one form of the device of my invention.

for use in my device.

Figure 5 is a section through the line of Figure 3.

Figure 6 is a section through the line 6 6 of Figure 5.

Figure 7 is a section through the line 7-7 of Figure 5.

Figure 8 is a section through the line 88 of F lgure 7.

Figure 9 is a broken section of a modified form of key with method for its employment.

The particular form of the device of my invention, shown inthe accompanying drawings, comprises a shell 10, having the openings 11, 12 and 13; Vithin the shell 10. and carried thereby, is a revolubl'e key plate 14, having an elongated opening 15 capable of allowing the passage of a key. \Vithin the casing 10, and in alignment with theopening 13, is a revoluble pin cylinder comprising the cylinder casing 16 and the cylinder 17. The revoluble cylinder 17 has the three spaced projecting lock members 18, '19 and 20 and a series of pin chambers 21, 21, 22, 22, 23, 23, 23, 23, the chambers being concentric with, but in a different circumference from, the chambers 21, 21, 22, The end 24 of the casing 10 has series of driver chambers 25, 25, 25, in alignment with the pin chambers of the cylinder 17, when the deviceis in locked position.

WVithin each driver chamber 25, in alignment with the pin chambers 21, 21, 22, 22, is a driver 26, abutting upon which is a spiral Figure 4 is a plan view or a key suitable spring 27, maintaining the driver 26 in a position across the jointure line between the revoluble cylinder 17 and the non-revoluble member 24, thus preventing the cylinder from revoluble movement.

Within each pin chamber 21, 21, 22, 22v is a movable pin abut-table upon a driver '26, the length of the pin 28 being such that with the non-revoluble member 24 when the device is in normal position, and so maintained by a spiral spring 30 abutting upon a shoulder of the pin 29 and affixed to the wall of the chamber 23. If the false pin 29 is forced inwardly, it will be positioned across the jointure line of. the cylinder 17 and the member 24:, thus preventing the former from revolving, the pin 29returning to its original unlocked pos tion when the force is removed.

The pin chambers decrease slightly in diameter toward the opening 13, in order that the pins may not fall therefrom.

A pin 31, carried by the member 24-, extends into a chamber 32 within the cylinder 17 and acts as a supporting member for the cylinder. q

The cylinder 17 is. so'positioned as to allow a bit chamber 32 between its eX- tremity and the plate 13, for purposes described later.

A spring 33, abutting upon the cylinder member 19 and the wall of the casing 10,

tends to return the cylinder to a locked position when the unlocking force isremoved.

A stop pin 34-, abutting upon the cylinder memberv 19, prevents the cylinder from revolvingbeyond its predetermined locked position. v The end 35 of'the cylinder 17 has an elongated opening'36, which can be placed in alignment with the opening 15 of the member 14.

Bevoluble through the openings 11 and 12. of the casing 10, when the cylinder 1? is revolved, is a split ring 3'7, having re cesses 38 and 39. capable of receiving the members 18 and 20 of the cylinder, the ends of the ring 37 being capable of practical abutmentupon the member 19 of the cylinder 17.

A key capable of operating the described device is shown in Figure 1 and comprises a flat shank 10, having the pin-engaging members 11, 4.1, the shank 40 being extended through the shaft .2 to the flat bit 4-3, having the pin-engaging membersis, 44:, the bit 48 being positioned at right angles to the shank 4:0.

The operation of the device is as follows, the device being in the locked position shown in Figure I The key bit 44% is passed through the openings 15 and36 until it is within the bit chamber 32, and is then revolved 45" until the shank 40 is in alignment with the openings 15 and 36. when the shank 40 is passed therethrough. The key is then passed inwardly, the bit 14 and the shank tioned outside of the casing 10, and the lock can be removed from a staple through which the ring has passed. The key can then be removed from the lock, if desired. The cylinder 17 is prevented from returning to its'oiginal position by the abutment of the members 18, 19 and 20 upon the closed portion of the ring. v

WVhen it is desired to lock the device, the ring 3? is revolved until, the open portion is returned to its original position,

when the spring 38' causes the members 18 and 20 to enter the recesses 38 and 39 of the ring and the member 19 to position itself between the ends of the ring, the stop pin 34 preventing the cylinder from further movement. 7 V r It has been found'possibleto pick locks of the pin-tumblertype by inserting wires, or similar devices through thekey opening and forcing the pins inwardly'to allow of the revolution of the cylinder. It is evident, upon a consideration of my device, that this is renderedextremely difiicult, if not. impossible. If a wire is inserted and either of the pins 29, 29, 29, 29 forced inwardly,

the movement will lock the device instead of unlockingit. In order to pick the lock, it is therefore necessary to force the four proper pins inwardly and not to force any one of the other pins inwardly.

The above description has been limited to a flat key, but it is evident that a barrel key may be as readily eniployethwis is shown in Figure 9. In this modification,

the member 31 has been extended and re It is evident that a plurality of key bits may be employed, that they may be at any angle with respect to each other and the key shank, and that they may have a wide variety of pin-engaging members, thus allowing of an almost indefinite number of key shapes.
